EDAN F300 Fetal Patient Monitor Speaker BS 5090B38C 20Ω 5W Replacement Audio Component

EDAN F300 Fetal Patient Monitor Speaker BS 5090B38C 20Ω 5W Replacement Audio Component

Introduction:

This product is a high-performance speaker assembly (PN: BS 5090B38C) designed specifically for the EDan F300 series fetal monitors. The speaker features a compact, circular design with a diameter of approximately 50 mm and a durable engineering plastic frame housing, ensuring secure mounting within the monitor's chassis. The speaker incorporates a high-quality ferrite magnet and a precision-wound voice coil, providing clear, distortion-free audio output across the frequency range required for fetal heart rate reproduction and alarm functions. With an impedance of 20Ω and a power handling capacity of 5W, the speaker is perfectly matched to the monitor's audio amplifier circuitry, enabling efficient power delivery and reliable performance. The speaker diaphragm is made of treated paper or polymer composite material, maintaining stable acoustic performance over long periods and adapting to various environmental conditions. The assembly includes an integrated mounting plate with precision positioning holes for secure mounting and is equipped with solder terminals or push-in connectors to ensure reliable electrical connections.

Key Functional Advantages

1. This speaker handles all audio output for the F300 monitor, providing real-time playback of fetal heart sounds and simultaneous alarms for abnormal heart rate, equipment malfunction, and probe detachment, offering reliable audible alerts for clinical monitoring.

2. Firstly, the parameters are perfectly matched: the 20Ω impedance and 5W power output are highly compatible with the main unit's output circuitry, eliminating noise and current hum without burdening the mainboard. Secondly, the sound quality is clear and penetrating, optimized for medical environments, ensuring clear delivery of critical alerts even in noisy environments like wards.

3. Constructed with medical-grade materials, it withstands routine disinfection and wiping, and is resistant to aging and deformation. The standardized installation structure allows for immediate operation after replacement without adjustment, significantly reducing equipment maintenance difficulty.

Installation and Removal Methods

Removal Steps: Before operation, turn off the monitor power and unplug the power cord. Locate the mounting cover corresponding to the speaker on the main unit. Gently pry open the cover by hand, then pinch the speaker's connector and smoothly pull it out; do not pull the wire directly. Next, press the spring clips on both sides of the speaker to gently remove it from the mounting slot.

Installation Steps: Align the new speaker with the mounting position inside the main unit. First, insert the connector firmly to ensure good contact. Then, press the speaker into the mounting slot. Once you hear the clips click into place, confirm it is securely fixed. Finally, replace the mounting cover. Turn on the power and test if audio playback is normal; the installation is complete.

Usage Precautions

1. Disassembly and assembly must be performed with the equipment powered off. Do not plug or unplug wires while the power is on to avoid short circuits and damage to the speaker or main unit.

2. For cleaning, simply wipe the outer casing with a soft cloth or disinfectant wipes. Do not spray or pour liquids directly into the speaker to prevent moisture damage to the diaphragm.

3. Do not touch the speaker diaphragm with sharp objects. Avoid forcefully bending the clips during installation and disassembly to prevent component breakage.

4. Use only the BS 5090B38C model, 20Ω 5W dedicated speaker. Do not arbitrarily replace it with other specifications to avoid parameter incompatibility and malfunction.

5. If no sound, distortion, or noise occurs, replace the speaker immediately to avoid affecting the normal operation of the monitoring and alarm functions.

6. Spare speakers should be stored in a dry, dust-free environment to prevent moisture and dust accumulation, which will shorten their lifespan.
